Larry, et all,
Got it installed yesterday. Piece of cake! Took all of about 2 hours and
that's with the mandatory one hour running back and forth for tools (and
beer). Didn't need the diode either. Mounted the module under my seat. It
does get a bit warm but not hot. Tie-wrapped everything nice and neat. Looks
good.
Took about another hour of tweaking (still not done). Pinging was very
noticeable and much more metallic sounding than my exhaust manifold leak so
it was easy to tell when it was detonating! I did notice I got a bit of a
reduction in power on big hills though (which is bothersome) when I had it
setup to stop the ping. I have been fiddling with the timing on the fly
trying to get it just right. Also noticed there is a VERY fine line between
advanced enough to ping under load (with sensitivity turned lowest) and too
hard starting. Retard the timing just a hair and it starts fine but then no
ping even w/the unit on lowest settings. Seems awfully picky but then that's
what JB said too. I'll bypass it, set the timing to just ping and then redo
my adjustments again.
Those that have them... do you know if you can adjust the EKE module on
the fly or does it read the adjustment settings only on startup? I had to
drive and adj so I would always stop and shutdown with each change. Seems
two people would make these adjustments go a whole lot easier.

I like the idea of the EKE and want to install it but would like to be able to
adjust it from on the fly from the dash or arm rest area.

Would it be a hard thing to solder a couple of wires to the connectors for the
adjusting variable resistors, and run them to the dash. In the dash you could
install variable resistors to match. You might be able to improve the
sensitivity problem by determining the best range for the adjustments by
measuring the resistance of the original resistor e.g. 30-90 ohms, installing a
resistor that was 30 ohms and installing a variable resistor with 60 ohms
resistance in series. This would make the adjustment 270 degrees of rotation vs
the very small adjustment you are describing allowing you to adjust gradually.

P.S. I was an electronics geek when I was 11-13 years old. I probably have
forgotten most/all of what I used to know. Dont laugh if I am wrong. Several of
you have much more recent/complete knowledge in the area.

Emery,
I've had my EKE in for a week with a good test pulling the TOAD behind it.
I set the max retard to about 3 (10 degrees or so) and the sensitivity about
3/4 of full range. It took one tweak to get it where I wanted. Are you
suggesting that it needs adjusting so often that dash mounted remote
controls would be a good idea? I had closed the hatch and hoped not to open
it again until I return from Florida in July.
Regards.

Great idea! This sure sounds as if it could be done. I was even thinking
of
using a choke cable that could be rotated from the dash but couldn't figure
out a good way to connect it through the adjustment hole to the variable
resistor. I hope that you do the electronic method and then let us other
owners know what parts you used and your procedure. Since I cannot hear the
frequency of the pinging, I also want to build the knock sensor light that
will come on when the engine pings. This is detailed on Gene Fisher's site.
It essentially stretches out the pinging pulses so that they can been seen
on
a light indicator. This could be put right alongside your variable control
knob on the dash or on the driver's left side panel.

When Emery and I did mine, he put a board under the deck which would let him
adjust it on the fly. It is easier with two people, but not the most
comforatble.

Ron,
It's not the EKE module itself thats touchy in my case... it's my
distributor and timing. I.m hoping theres not alot of adj. needed for the
long haul. It's a great idea though.
